I have run into a really odd issue with my USB hard drive (SimpleTech box w/ Fujitsu 160 GB drive).
If I have the drive connected at boot, it is fine. If I plug it in after the initial USB probe, it connects at full speed. At 12Mbps, it is pretty useless. It can take a couple of minutes just to mount. If I disconnect it (either after dismounting or before mounting in the first place) and then re-connect it, the drive is probed correctly as high speed and it is actually useful. Further disconnect/re-connect operations always seem to probe it a high speed. Only the first time the drive is plugged in after booting seems to fail to connect at high speed. Here is my usbconfig with the drive probed correctly. ugen0.1: <UHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen1.1: <UHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen3.1: <UHCI root HUB Intel> at usbus3, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON ugen4.1: <EHCI root HUB Intel> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen4.2: <product 0x4482 vendor 0x04b3> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=SAVE ugen4.4: <SimpleTech SimpleDrive PS> at usbus4, cfg=0 md=HOST spd=HIGH (480Mbps) pwr=ON ugen2.2: <Biometric Coprocessor STMicroelectronics> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON If it probes as full speed, it is almost the same except that it is: ugen1.2: <SimpleTech SimpleDrive PS> at usbus1, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON System is 8-Stable i386 uniprocessor and I have been seeing this since v8 went into the release cycle. It's just an annoyance now that I realize what is going on, but I would like to see if anyone else has seen this and if there is any explanation. -- R.
